Specification of Letters Patent. Pa'tnted 'sept. 10, 1918.

' Application nan December as, 1911. Seria1208,! )27 5% all whom it may concern:

Be it known that I, FIPANKLIN 1?). Armor, a citizen of the United. States, residing lat Galion, in. the county of Crawford and State of Ohio, have invented certain new and usefuLImprovements in Fuel-Vapor as improving and increasing the vaporizationof high grade fuels, such as gasolene, and securing the maximum amount of completely vaporized mixture fromv any fuel used, s that they may be utilized in the .20

operation of motor vehicle engines. It is another obyect of theinvent on to provide a vaporizer for the abovepurpose which. may be used asxan adjunctto the intake and exhaust manifold with WlllCh the engine is equipped, or may itself constition to sovide a fuel vaporizer including generallyan. outer shell or casing within which formed separate exhaust receiving chambers corresponding in number with the 'niu'nbcr of exhaust ports of the engine, said casing also having intake port connections and means for causing a circulation. of the charge around and in. contact with the walls of said exhaust chambers prior to its ad mission to the intake ports of the engine cylinders. i "It is also animportant object of my invention to provide; in a vaporizing appa ratus as above characterized, means whereby an equal distribution of the vaporized mixture to the intake ports of the engine cylinders may be effected.

.And it is a further general object of my invention to. provide a hydrocarbon fuel nporizer which is relatively simple in con sir-notion aswell as efl'cctirc and reliable in practical use, m be readily applied to the various tr" ()fll'lOl'Ul vehicle engines, and by the use of which appreciable economy may be realized in the operation of the manic;

With the ahi'n'e and other objects in View,

' the in'vz-intion consists in thenovel features of construction, combination and arrange ment of the several p'arts as will be hereinafter more .fully described, subsequently claimed and illustrated in the accompanying drawings, in which similar reference characters designate corresponding parts throughout the several views and wherein.

Figure 1 is an'elevation partly in section showing my improved vaporizer applied to a motor vehicle engine in conjunction with intake and exhaust manifolds, such for in stance as are found in-t-he Ford type of engine;

Fig. 2 isa transverse section takcn 'on the line 22 of Fig. 1; i

Fig. 3 is a vertical section taken on the line 33 of Fig. 1;

Fig. 4 is atop plan view partly in sec-' designates the outer shell or casing of the yaporizer whiclnfor purposes of illustration 1 have herein shown as operatively applied to a four cylinder engine.

The shell or casing 5 is preferably formed with longitudinally tapering end portions 6 which are divided from the bodfportion of the casingby vertical artitions 7, In spaced relation to each 0 these partition walls 7, a continuous transverse wall 8 in:- tegrally connects the opposite. side walls of the casing and incloses or defines the ex haust receiving chamber 9 which is preferably of rectangular form and has its longer dimensions extending longitudinally ofthe casing. The top and bottom walls of tlnschamber are equidistantly spaced from the corresponding walls of the outer shell or casing 5 to provide passages for the mix-. ture, as will be'herelnafter more fullyfre lated,

Between each of the "vertical partition walls 7 and the opposed end wall of the chamber 9 and integrally connecting said walls there is a centrally located-vertically tegral with the end wall of the eXhaust reeeiving ehaiiilier and with the partition \vall'i'. I 1

One side, wall of the easing 5 is formed with exhaust inlet openings 12 and 13 which I'LHIMYCtlVOlY eonnnuiiieate with the hollow tapered ends of the, casing and with the spared cliainhers'll. Bored lllgH it and reopeetively are. integrally formed on the partition "walls 7 and upon the walls 8 and are adapted to reeeive the usual attarhing holt'a whereby the shell or easing is securely fixed in position with the openings 12 and 13 in connection with the (Xlltltlml ports of the, engine -e vlinders. In the opposite ide wall of the easing" Tillie outlet openings 1t and 17 respectively for the.exhaust-gases are provided, and to these opening a the exhanst manifold indicated at 18 is connected through whieh the exliamt gas is delivered to the mntlleir.

19 designates the intake openings in one side Iwall of tlie easing 5 which regiater with the intake ports of the engine i vliudersi and "1.5 :912$1iii 1201 ier the P lP ite side of the hallie, \vall ll l iii the the side wall of the easing, 5. lo these latter openings. the intake manifold 31, leading from the earliureter connected. .Tn the operation of the deviee as above 5 deerribed, it will he i'uiderstood that the exhaust gases from the engine cylinders are delivered through the ports I) and 13 into the tapering ends of the easing i and the several elianiliers 9. Thus the. walls of these el'iamloers and the partition walls 7 become liiglily heated as tliegaa expands in the Several ('lltHlllnlH. It will he understood that; there is no iiiipeiliineiit to the passage of the gases, which enter the exhaust manifold 18 through the openings l7. The walls 7 and. S are however heal ed to a very hig'li degree. Ifhe kerosene or other low grade 11 ydi'oiiarbon fuel mixture eiiters tlie easing 5 through the openings 20 l'ron'i' the intake manifold and is delivered against the ha the plates 10. "The F! Qtioii tihrongli the intaite openings 19 'in. the operation of theengine.-draws the fuel gas longitudinally 'lie ieath the elianilier walls 8 to tho renter of the easing-5, then upwardlyla-tween these'rlianiliers and 'lt)l;\-

At the top 66 of the ehamberss 9 an i at the center of the device will he at .onre manifest.

easing the division of the mixture occurs,-

and it, is drawn in substantially equal ,vol-

ini'ie in opposite directions over the top walls of the ehamhera J to the respective intake In this manner, it will be ap- [)I't'tlttlfll that kerosene and ot'lier relatively heavy fuel. can lie satisfactorily used as the propelling niediuiii for motor vehicle engines and owing to the complete vaporization of shell lrvdroearlain fuel, pert'eet comwhich e asi' leni'i -oisin'iilar' refined hydro- -earbou fuelS may he initially suppliedto the engine e vlinders. Of course aftertlie engine has been started and the walla Tand 8 have heeoiiie sutlieiently heated, the operation of the engine is continued with the use. of the low grade fuel.

In Fig. 5 of the drawii'igsi I have shown my iii'iprovei'l vaporizer applied to the englue e vliiider as a substitute for the usual intake manifold. [11 such eonsti'uetion, the bottom wall of the casing 5 is formed with oose iieeh extension 23 for connection to the earliureter. 'lliix gooseneck extension preferably integral with the. casing wall at the center thereof and delivers the 'mix-' ture against the bottom walls of the chainlWlH E) to lie drawiiaround said chambers and into the engine eylindera in the manner aliove. explained. The exhaust-n'ianifold 18 is of eourse eonneeted to the outlet openings of the :aeing 5 to exhaust the gases in the eanie manner as in the en'ibocliment of the invention shown iii-Fig; 1.

' Fronif the foregoing description taken in minnectioii with, the. accompanying rlrawinge, the construrtionl, manner of operation and beveral advantages of my invention will be clearly and fully understood. The 1 1l1'l proved vaporizer 15" of very simple construeftione and while it is i'lesigned primarily for use in connection with the, Ford type of motor vehicle. enginegit is apparent that. by resortingto iiiinor struetln'al alterations the device inight lie adapted for use in e'onneetion-witli various other types of such engines. In practice, it has beeir found-that the device satisfactorily zitt'OlliPllHlltS the in tended purpose. and enables tl'ieen'gine to be operated on low grade liydroearbon fuels with a. iiiaxiiiiuni of power eltieieiiey. As such fuels are proeurable at considerably less root than the refined liydiroearlion-fuels, the epoiioinv resulting froni the use ofthe The con- Hl'l'lliftlml and relative proportionsof the Seie 'alpart-s of the vaporizer as indicated in the. aceom ia ii in' clr'awin Iha-ve found i t 7 v .to be. productive of the best results. It is? -however-tcfbe understobd that the several structural features of the device are susceptible of numerous modifications, and I accordingly reserve the privilege of adopting all such legitimate changes therein as may be fairly embodied within the spirit and sec e of the invention as claimcd.
